User-Signed Uploads for High-Assurance Ingestion

Prepare uploads server-side and let users sign with ArConnect when private-key custody must stay outside Evercore. Best used as a protocol extension, not the default onboarding path.

Prepare a data item server-side — encrypt, validate, tag — receive it back unsigned, then sign it in-browser with ArConnect. The server never touches your private key.

Keep authorship and payment on the user side without losing platform control.

User-signed uploads let product teams support non-custodial publishing while still using Evercore for preparation, validation, and downstream operations.

Value

Reduce custody concerns

The platform prepares the item, but the end-user signs it, which keeps the most sensitive trust boundary off the server.

Support creator and wallet-native products

User-paid or user-authored uploads are easier to justify when the server never becomes the hidden signer.

Keep the rest of the platform available

Profiles, traceability, and post-upload workflows can still run around a user-signed artifact.

For operators

Prepare canonical data items server-side so client wallets only sign a clean final payload.
Pair with ArConnect for challenge, identity, and wallet-session flows in browser products.
Use SmartWeave or billing modules when signed uploads trigger monetization or gated access logic.

For buyers

Useful for marketplaces, creator platforms, member portals, and wallet-native apps.
Helps remove objections from teams that do not want server custody of user signing authority.
Strengthens the Web3 story without abandoning enterprise controls around the rest of the workflow.
